Hydraulic Force

A hydraulic force is generated any time pressure acts on an area. We are concerned about force because it is the forces created within the pump that:

  • Deflects the shaft.
  • Causes mechanical seal faces to go “out of flat”.
  • Extrudes elastomers.
  • Creates excessive axial thrust .
  • Causes many vibration problems.

Any time you change the velocity of the liquid in the pump the pressure changes also, and it is this change in pressure that causes some of the unwanted hydraulic forces that are being generated.
